Power Efficient 3D Application Performance
The NVIDIA Quadro K420 delivers power-efficient 3D application performance and capability. 2GB of DDR3 GPU memory with fast bandwidth enables you to create complex 3D models, and a flexible single-slot and low-profile form factor makes it compatible with even the most space and power-constrained chassis. Plus, an all-new display engine drives up to four displays with DisplayPort 1.2 support for ultra-high resolutions like 3840 x 2160 at 60 Hz with 30-bit color.

Designed and built specifically for professional workstations, NVIDIA Quadro GPUs power more than 200 professional applications across a broad range of industries including manufacturing, media and entertainment, sciences, and energy. Professionals trust them to realize their most ambitious visions— whether its product design, visualization and simulation, or spectacular visual storytelling—and get results to market faster.
